[TYPO3] Typo3 adds _1.jpg, _2.jpg etc. when choosing same image for background

[Brian Bendtsen]

Hi

I have a site where the users can change the background image. The TS 
setup looks like this:

lib.singleImage = IMG_RESOURCE
lib.singleImage {
   # Default image if no image is inserted on the page
   file =
   file.import.data = levelmedia: -1, "slide"

   #Folder to upload the userdefined images to
   file.import = fileadmin/user_upload/portefølje - websize/
   file.import.listNum = 0
   file.import.override.field = media
   stdWrap.wrap = background: url( | ) no-repeat;width: 100%; height: 
100%; background-position: center center;
}

The problem is, when they choose the same image for some pages the 
imagename is followed by _1.jpg or _2.jpg and then it cant be found.

How do I work around this?
